uhm, no? you are free and open to say MLK was a womanizer. like literally right now you are allowed to post this onto HN with no repercussions to your well being. try printing that mao was a womanizer in a chinese newspaper.
There's a difference between biased reporting and citizens being forbidden from talking about something online.
If you made the same post but about some Chinese politician and in China, you could get in trouble for that.
